  • Absorption and controlled release of polyethers from hydrogel biomaterials
    Publication number: 20040115270
    Abstract: The present invention is directed to an ophthalmic solution for soft contact lenses for controlled release of polyethers into an eye's tear film. Polyether components of the subject ophthalmic solution are released from the soft contact lens material matrix over long time periods to produce longer lasting wetting performance, improved lubricity, improved end-of-the-day comfort and reduced feeling of dryness from wearing contact lenses.
